Intel Mac :: It Connects To One Network But Not The Other?
Mar 12, 2012
Until now I have been connecting to a wifi network that I use at home. It is fairly slow so for large system updates I connect to a wifi dongle. When this wasn't working last week for the new system update, I came onto the forum and was advised to change the DNS settings for the wifi dongle. It all worked. Since the system update however, my existing network will not connect to the internet at all. It appears in the wifi list but won't connect to the internet. Also, when I started to look for a solution I realize that I do not have Airport as a choice in the wifi list in preferences.

Software Update ran yesterday and I installed the AirPort Utility update (version 5.5.2), and now my MBP no longer connects to my home network when the SSID broadcast is disabled. When I enable the broadcast the network shows up in the list of available networks and I can connect to it, then I can disable it again and the MBP stays connected. But if it's disabled to begin with it won't connect.
I never had this problem before the update, and no other devices on the network are having any issues. Has anyone else had this problem yet, or know of a fix?
Late 2008 unibody Macbook Pro running 10.6.5, all software is up-to-date except for the latest update to iTunes.

When I arrive at my office and turn on my MB Air, it does not always connect to my wireless network, it sometimes connects to an un-secured wireless network locaterd somewhere else in the building. Is there a way to force Lion to always connect to a specfic network and ignore others?

I have a 27 inch, mid 2011 imac. I bought it in March. It has started losing its wireless connection. The other issue is when it does connect it is very slow. I have a netgear modem, I dont think this is the issue cause the IPAD, and wireless laptop connect fine. I've also run a speed test, all wireless devices connect to 10Mbps and LAN devices connect up to 30 Mbps including the iMac when it is wired. Could this be an issue with the airport card? How would I know, how do I check? What should I do?

The screen on my macboook pro, 13inch, was messing up earlier, flickering and all.
I got trigger happy and decided to take the glass bezel off my MBP (I've done it before) and managed to disconnect the LCD screen from the rest of the MBP.
However now I can't accurately connect the LCD screen back to the cable it's connected to at the base of where the lcd screen would go.
I'm checking out the videos on PowerBook Medic for the macbook Pro and am seeing how they take off all these things such as the SuperDrive, fans, logic board, etc....but rather than taking off every single item am wondering which of these to take out in order to be able to pull out that cable ever so slightly, simply so I'll then be able to connect it to the LCD screen..
I'll keep researching online and also hope for any guidance tonight, seei as id really like to get this issue resolved before the night ends...not forcing me to leave a tangled MBP on my desk overnight.

I've had my Mac for 3 years and never had a problem with Airport Express. If I did, I would usually turn it off and then on again and it solved the problem. The last two weeks I've been using a wi-fi hotspot near my home until I get a proper internet connection at home. Suddenly, my internet stopped working. The airport recognzies the link and still connects but the internet page says i'm not connected to the internet. I've tried using diagnostics and it says it can't fix my problem. In diagnostics, the first 3-4 lights turn on, but the last two are either yellow or red. I've changed the time to make sure it was correct, I've re-started the computer several times and it still doesn't work. I don't know what it is that is not working. The airport recognizes the signal, yet I get no internet connection. And I haven't downloaded anything recently.

Novice at VPN here, but it looks as if nothing is being encrypted when I'm connected over VPN.
Setup:Client: OSX 10.5.4, connecting to a server: OSX Server 10.5.4 via Apple's built-in VPN system.
Scenario:
� I've set up OSX Server on an XSERVE to allow VPN connections.
� I've set up the shared secret, and an account for logging in with.
� I've set up the client machine with VPN to use that shared secret, along with that username/password account.
� I've made sure to check the box "Send all traffic over VPN connection" on the client. Seems kind of silly that it's even an option, what would be the point of VPN otherwise?
� Connect: Client connects to server through VPN, no problem! It authenticates and the connection timer starts and everything is grand. We are connected via VPN!
� Begin packet sniffer on client machine in the terminal.
� Load a web page.
� Packet sniffer reveals that everything sent and received is good old plain text - NOT encrypted - just like we were not connected via VPN.

iBook G4 shows that the airport has full connectivity (full bars) yet it doesn't connect and states that there is no IP address. The iBook connects using its internal airport to a Netgear Router. There is a PC that runs windows that is connected to the cable modem. For a month or so both computers were able to access the internet simultaneously. All of a sudden the computers are unable to access the internet at the same time. When I attempt to connect at the same time my Mac gives me an error stating that another IP is in use and so I can't connect.
How can I give my iBook an IP address so that both computers can be online at the same time?

I've been having an issue with my wireless for a while now where each time I turn on my Macbook it auto connects to a neighbours wireless rather than my own despite it being set as the default location.
I've tried trashing preferences, rebuilding my wireless configuration etc... but it still connects to my neighbours wireless and not mine.
Also, it's recently decided that each time they turn on or off their wireless it'll temporarily interfere with mine and kick me offline (it doesn't do the same for my girlfriend who is connected through an Acer laptop)
Is there a way to change this?
It's not too much hassle manually changing networks but enough of one that I'm posting this thread!

I've just received my new Nehalen MacPro. Everything went fine except one thing that its making me crazy. I have a windows share on my office network, to which I can connect just fine with my Macbook. On the MacPro I can connect to a WindowsVista machine (same/user and pass than the MacPro) but cannot connect to fileserver.
Whatever I try, the finder always connects as guest, even after I chose "connect as" as fill with the right username/password. Finder says its connecting and the connects, but as guest and not as my user. Because the guest has no permissions on this share, I see the folders but no files.

My iBook G4 is having network issues. Since waking from sleep, it will connect to my Airport Extreme base station, but I can't access the web, or access the router from Airport Utility.
Things I've tried so far:
*Rebooting
*Resetting the router to factory defaults
*Swapping out the router for a Linksys
*Clearing out network passwords from Keychain
I doubt it's a hardware issue, as everything works in Tiger (booting from an external drive).

i was wondering if there is a device that works as a usb hub, but connects to the computer wirelessly via bluetooth to your mac. i think this would be nice since i will have a station where my macbook pro will go every night when i buy it and i would like to simply open it and have it connect to the monitor, printer, speakers, etc. without plug in in a bunch of cables.

My computer is connected to the wireless internet, and other devices such as my brother's laptop and my cell phone are connected and working off of the internet fine. However, my computer is not loading webpages, sometimes it does, sometimes it doesn't. It just all of a sudden stops and the blue bar won't go any further. I tried running the safari under the guest account and it worked fine.

I got a very weird problem. When I connect my computer (Macbook, Mac OS X Leopard) via cable to the router all my applications work with no problem. I can browse the internet, visit the itunes store, receive mail, get updates on my dashboard.
But when I am connected to the internet via wifi (on the same router) I can still browse the internet while all other apps cannot connect to the internet. Itunes says it cannot connect, mail says it cannot retrieve any mail etc.
I have tried on a different router at a friends house. Same thing. Everything works via cable but wirelessly only the browser works and nothing else.

MBP dropped connection and now all I get is an exclamation point where it used to show full bars. This happened right during a time I was online using Chrome! I tried restarting the MBP, resetting the router (or whatever that is called), removing and addine AirPort under System Prefs but nothing works. I'm using the iPad 2 to access the Internet and write this, so I know it works. My iPhone also connects just fine. Just the MBP that suddenly dropped and cannot connect.

New to a Mac and I just received my new MBP Retina two days ago. I am having a strange issue where right after i turn on the computer it will connect and drop my wifi connection over and over again. If i turn wifi off and back on again it fixes the issue.
I have the latest updates for the MBP so not sure if this is a hardware issue or a software bug. My router is also brand new from Linksys and is working flawlessly once i do the above steps.

Whenever trying to connect to a WPA2 Enterprise WiFi network, I only get an IP address when it is the first time. (Authentication in itself works fine, it is getting an IP address that is the problem.) What I mean is the following:
1. I start up the computer
2. I connect to the network just fine
3. Suppose now I turn Airport off
4. Then I turn Airport on again
5. Now it doesn't work anymore! I still get authenticated (PEAP) fine, but I now get a "self-assigned IP address" and can no longer connect to the Internet.
6. When I restart, the same happens, i.e., "go back to step 1"
It seems as if the computer keeps a wrong cache of something, which is only cleared after restart?
It is not a big deal, would have been worse if I couldn't connect at all, but still quite annoying that I have to restart every time.

Recently got the new Mac pro and the internet connects briefly via (wire less) and then disconnects after 30 secs. I notice the DNS server switches numbers. After this happens I no longer have internet connection.
Connecting via ethernet is no good either. It doesn't connect at all. I did do a migration from another system. I am wondering whether the setting were saved from my previous system and are getting corrupted with the new system.

I've been having problems staying connected on my Powerbook G4. The wireless works perfectly but the ethernet does not. I've been using the dorm ethernet jack to connect. The problem is that my computer can't maintain a consistent connection through ethernet so it randomly connects and disconnects. I called my campus' IT department and they told me that it must be my computer because they're system said that it didn't detect my computers IP address. I called Applecare and the person told me that it must be something wrong with either the network card or the ethernet port. Anyway, he gives me a case number so I can go get a repair. Unfortunately an Apple Store is far away from where my school is so I went to my school's bookstore instead.
The bookstore is an authorized service place. I drop the computer off to them and they sent it to Apple. I got a call today from the bookstore guy saying that the Apple technicians discovered that "liquid" had gotten into the motherboard and refused to service my computer. I was really angry when I heard this because I keep absolute care of my laptop. I know for a fact that no water has ever been around my laptop. I'm guessing it must have been negligence on the bookstore's part. I declined the $1300+ repair estimate so now its on its way back to me. I have a brother that works at the Apple Store and he just suggested going directly to an Apple Store this time. Will they just refuse warranty repair again?

Each time I have my MacBook Pro up and running, with my Apple Mail app running and I connect via FaceTime to someone, the mail program starts making tons of nosie as if it's sending and receiving mail over and over and over and over again. I have a 2/2011 MBP 15" maxed out.

My late 2011 MBP (lion 10.7.3) used to connect to external displays through a VGA cable. It has stopped doing so since recently and I am trying to find out why, and how to fix it. The only changes I've applied to the system are (1) connect to a Thunderbolt display and (2) installed gfxCardStatus. The MBP and Thunderbolt display work flawlessly together, with network, USB, and firewire connections operating. gfxCardStatus has noticably increased my battery life (so I recommend it) and I'm aware that it needs to be in dynamic or dedicated GPU mode for external displays. The VGA external displays do not work when gfxCardStatus is running in either dynamic or dedicated mode, or when I disable gfxCardStatus completely so that it does not show on the process list.

I have no trouble using WiFi at home. But when I connect my new MacBook Pro to WiFi networks at cafes, airports, and hotels, I can connect and a page or two will load without a problem. But a minute or two later, the WiFi signal appears to be fine but no pages will load and e-mail messages can't be sent or received.
If I turn WiFi off and reconnect to the same network, I can load another page or two and then it quits working. I don't have this problem when connecting to the same networks on my iPhone, so I'm assuming there's a problem with my computer or its settings.
